Angelonia plant named ‘Balangdaros’

ABSTRACT

A new and distinct cultivar of  Angelonia  plant named ‘Balangdaros’ characterized by its rose-pink colored flowers with darker pink spots, medium-sized flowers, and moderately vigorous, upright growth habit.

Latin name of genus and species of plant claimed: Angelonia angustifolia.

Variety denomination: ‘Balangdaros’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Angelonia plant botanically known as Angelonia angustifolia and hereinafter referred to by the cultivar name ‘Balangdaros’.

The new cultivar was developed by the inventor in a controlled breeding program during January 2003 at Arroyo Grande, Calif. The objective of the breeding program was the development of Angelonia cultivars with unique flower colors, continuous flowering and moderately vigorous, freely branching and upright, growth habit.

The female (seed) parent of the new cultivar was the proprietary Angelonia angustifolia breeding selection designated BFP-895, not patented, characterized by its large dark purple-colored flowers, dark green-colored foliage, medium vigor, and upright growth habit. The male (pollen) parent of the new cultivar was the proprietary Angelonia angustifolia breeding selection designated BFP-873, not patented, characterized by its dark purple-colored flowers, dark green-colored foliage, medium vigor, and upright growth habit. The new cultivar was discovered and selected by the inventor as a single flowering plant within the progeny of the above stated cross-pollination on September 2003 in a controlled environment at Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since September 2003 at West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balangdaros’ as a new and distinct cultivar of Angelonia plant:

-   -   1. Rose-pink colored flowers with darker pink spots;     -   2. Medium-sized flowers; and     -   3. Moderately vigorous, upright growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in flower color and from plants of the male parent primarily in flower color.

Of the Angelonia cultivars known to the inventor, the most similar to ‘Balangdaros’ is the Angelonia cultivar ‘Balangroki’, not patented. However, in side-by-side comparisons, plants of the new cultivar differ from plants of ‘Balangroki’ in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describe the colors of ‘Balangdaros’. The plants were grown in 10 cm pots for 11 weeks in a greenhouse at West Chicago, Ill.

FIG. 2 illustrates a close-up view of the inflorescence of ‘Balangdaros’.

FIG. 3 illustrates a close-up view of the individual flowers of ‘Balangdaros’ showing variation in color from first open on left to fully mature on right.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where color terms of ordinary significance are used. The color values were determined on Apr. 13, 2005. The readings were taken between 1:00 p.m. and 3:00 p.m. under natural light conditions.

The following descriptions and measurements describe plants produced from cuttings taken from stock plants and grown in a double polycarbonate-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in 10 cm pots for 11 weeks while utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 75° F. to 85° F. (24° C. to 29° C.) during the day and approximately 62° F. to 70° F. (17° C. to 21° C.) during the night. Greenhouse light levels were maintained at approximately 6,000 to 10,000 footcandles during the day.
